Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573312, here are decompositions:

53 + 31573259 = 31573312
59 + 31573253 = 31573312
101 + 31573211 = 31573312
149 + 31573163 = 31573312
179 + 31573133 = 31573312
431 + 31572881 = 31573312
443 + 31572869 = 31573312
503 + 31572809 = 31573312

Showing the first eight; more decompositions exist.
